Abstract

Support base for railing (41), characterized in that it comprises a body (12) for receiving a post (3) railing and a front plate (13) fixed to the body (12). Such a base can be attached to a vertical surface of a parapet (42). It allows to mount the guardrail on the side of a terrace (6) without damaging the seal (43) of the terrace. The invention also relates to a railing system comprising such a base.

Description

The present invention relates to a device for supporting a railing particularly adapted to be used for securing a roof terrace. The protection against falls of people who have to circulate on a slab in height, especially if this slab is that of a roof terrace, is generally provided by a peripheral protection. A railing is usually installed, which includes posts, each fixed to a base and horizontal rails carried by the posts. When this slab is a slab of a building under construction, a temporary railing is usually installed, the base of which can be fixed or placed on the slab. The bodyguard is advantageously completed by a plinth which prevents the fall of an object or a person who would slide on the slab, under a rail. To ensure the stability of the railing when the base is simply placed on the slab, the base is generally connected to a counterweight by a cross member. Many existing buildings, generally old, have a roof terrace surrounded by a parapet whose height is insufficient to ensure the safety of a person circulating on the roof. In this case too, it is advisable to be able to put in place a guardrail, preferably permanent, to ensure that a subsequent intervention can be done safely. 1 In either case, it is important that the guardrail, temporary or permanent, can be put in place as simply and as quickly as possible in order to limit the risk for the team placing it. In existing buildings, the roof terraces usually have a seal that must be preserved during the installation of the guardrail. On the other hand, for aesthetic reasons or increased security, it may be necessary to provide guardrails inclined towards the interior of the terrace, relative to a bank of the slab.

The invention therefore more particularly aims to overcome these disadvantages by means of a support device, whose structure, relatively simple and inexpensive, can be easily mounted and is optionally easily removable. Preferably, such a device may allow the establishment of vertical posts or inclined relative to the vertical, and possibly the installation of skirting boards. To achieve this result, a device according to the invention is a base comprising a body for receiving a guardrail post and a front plate fixed to the body. The plate comprises means for fixing the base to a substantially vertical surface. This vertical surface is, for example, the inner surface of a parapet, so that the tightness of the protected terrace is not damaged by the installation of the base. These fixing means may be screw passages. The base advantageously comprises a space, formed between the body and the plate to accommodate at least one plinth. The body may advantageously comprise one or more longitudinal holes for the passage of a screw to block the plinth between the body and the plate. The body preferably comprises an upper housing, open upwards, to receive the lower end of the pole. This housing is advantageously designed to allow the installation of the post in two alternative positions, either substantially vertical or inclined.

The base may further comprise a substantially horizontal sole for laying the base on a slab. In this case, the body advantageously comprises a rear housing, open towards the rear and intended to receive the end of a cross counterweight. In addition, the sole may comprise fastening means, for example screw passages. Thus, a base according to the invention, comprising a front plate, a sole and a posterior housing, may alternatively be provided: fixed, permanently or temporarily, directly in a parapet and / or in a slab; or, placed on the slab and stabilized by a counterweight. In order to facilitate assembly, the base is advantageously formed by the assembly of two half-bases, provided to be functionally assembled according to a junction surface. Preferably, the junction surface is substantially a longitudinal plane. Preferably, the base has a generally symmetrical shape relative to this junction plane, so that each half-base comprises in particular a half-body and a respective half-platinum. Preferably, each half-base has, in said junction plane, two concave impressions corresponding to each housing. Fixing the two half-bases between them and with the post and / or the cross-member can be done by screwing, by means of screws which engage in pairs of coaxial bores made in the corresponding half-bodies, perpendicular to the plane junction. Advantageously, the base is provided so that the corresponding housing is narrower than the post or the crosspiece. Given this dimensional difference, the tightening of the screws causes a compression of the post and / or the crossbar which are engaged in the housing. This compression thus ensures effective fixing of the post or the cross member in the base. This attachment can be completed by a locking made by means of screws 29 - crossing the half-bases to engage (or only punch) in the post or the cross. If the post is metallic, especially when the railing is final, one can use a set screw to fix it on the base. This fixation can also be done or supplemented by a weld. A base according to the invention allows the easy assembly of the railing before completion of the final weld, which can be carried out away from the railing already close-mounted. The invention also relates to a railing system comprising one, and generally several, base according to the invention. Several embodiments of the invention will be described hereinafter, by way of non-limiting examples, with reference to the accompanying drawings in which: FIG. 1 is a schematic perspective view illustrating the general principle of a support device a guardrail mounted on a slab and using a first embodiment for a base according to the invention; Figures 2 and 3 are schematic perspective views of two half-bases together forming the base of Figure 1; Figure 4 is a perspective view of a second embodiment for a base according to the invention, mounted on an inner face of a parapet and carrying a vertically disposed pole; - Figure 5 and a view similar to that of Figure 4, wherein the post is arranged inclined rearwardly; Figures 6 and 7 are schematic perspective views of two half-bases together forming the base of Figures 4 and 5; Figure 8 is a perspective view of a third embodiment for a base according to the invention; and, Figure 9 is a perspective view of the second embodiment, illustrated in Figures 4 to 7, the base being mounted on an outer face of a parapet.

Figure 1 illustrates a railing 1 according to the invention. The guardrail 1 consists of a base 2 in which a post 3 is fixed vertically. The post 3 carries two smooth 4 substantially horizontal. The railing 1 is provided to secure the bank 5 of a slab 6, partially shown in Figure 1 and which may be the slab 6 of a building under construction or existing. The base 2 rests on the slab 6 near the bank 5. The railing 1 further comprises a crossbar 7 fixed by a proximal end to the rear, relative to the bank 5, the base 2. The crossbar 7 extends from the base 2 to the rear. A distal end of the crosspiece 7, opposite to the proximal end, carries a counterweight 8. In the example illustrated, the base 2 is arranged so that the crosspiece 7 extends substantially perpendicularly to the edge 5, in moving away from the base 2. The counterweight 8 increases the stability of the railing 1. The railing 1 is completed by skirting 9 extending substantially parallel to the side 5 and the smooth 4, in the immediate vicinity of the panel 6. A first embodiment of a base according to the invention will now be described in greater detail, particularly with reference to FIGS. 2 and 3. The base 2, illustrated in FIGS. 3, is formed of two half-bases 2A, 2B, each illustrated in a respective figure 2, 3. The half-bases are substantially symmetrical with each other relative to a plane of symmetry P for the base. In FIG. 1, the plane P is illustrated by a line which divides longitudinally the base 2. Each element of the base will be named left or right according to whether it is on the left or on the right of the plane P, such that would be seen from bank 5 if the base is in the position of Figure 1. In the figures, for the same element, the reference of its left part will be indexed A, and that of its right part will be indexed B. Thus, the FIG. 2 illustrates the left elements formed by the half-base 2A, and FIG. 3 illustrates the straight elements formed by the half-base 2B. The two half-bases 2A, 2B are provided to be assembled together with bolts, not shown in the figures, arranged through pairs of holes 22A, 22B vis-à-vis, each in a half-base respectively. The base 2 mainly comprises a sole 11, a body substantially parallelepipedal, extending upwards from the sole 11, and a front plate 13 substantially vertical, forming a square with the sole 11, in front of the body 12. The sole 11 is provided to rest substantially horizontally on a slab, as shown in Figure 1. It extends laterally on either side of the body 12 and comprises, in each half-flange 11A, 11B several through holes 16. The orifices 16 are provided for the passage of means, for example screws, for the possible fixing of the base 2 on the slab. Ribs 17 extend transversely under the sole 11, to limit the risk of sliding of the sole on the slab. The plate 13 extends laterally on either side of the body 12. The plate comprises, in each half-plate 13A, 13B, several through orifices 16, provided for the passage of means, for example screws, for fixing possible of the base 2 against a vertical surface, as illustrated with reference to a second embodiment, in Figures 4, 5 and 9. Thus, such a base can be used in several ways. It can be simply placed on a slab, fixed on the slab, or fixed against a vertical surface (see Figures 4, 5 and 9). The body 12 comprises a window 17, two housings 18, 19 and a recess 20. The recess is intended to lighten the base. The window 17 crosses the body transversely, that is to say from left to right and extends vertically above the sole. The window is provided for the passage and maintenance of one or two baseboards 9. It is set back a distance 17 relative to the plate 13, the distance D17 corresponding at least to the thickness of a screw head provided for fixing the plate 13. Among the housing, the housing 18 is provided to introduce the lower end of the post 3 of the railing 1, and the housing 19 is provided to accommodate the proximal end of the cross member 7.

The cross-member housing 19 is of rectangular cross-section, substantially identical to the cross-section of the proximal end of the cross-member, and open towards the rear, so that the cross-member can be introduced and maintained substantially horizontal. In the example shown, the width of the housing 19 is slightly less than the width of the crossbar 7, so that when assembling the half-bases 2A, 2B between them and with the crossbar 7, the crossbar 7 is there held by pinching between the two half-bases. Advantageously, a bore 21 is provided in at least one of the half-bases, through a wall of the cross-member housing 19, to introduce a fastening screw for the cross-member 7. The post housing 18 is open towards the top, and shaped to maintain the post in an erect position, either substantially vertically or inclined rearwardly. In the illustrated example, the inclination is of a value close to 30 °.

The housing 18 is provided to receive a pole whose lower end has a substantially rectangular constant section. Thus, the housing 18 has a shape that corresponds to a combination of a footprint 23 of a post in a vertical position and a footprint 24 of a post in an inclined position, shown in dashed lines in FIG.

In the illustrated example, the sum of the depths of the half-housings, measured perpendicularly to the junction plane P, is slightly less than the width of a post intended to be introduced into the housing. Thus, the assembly of the two half-bases by bolting through the holes 22A, 22B causes a pinch of the lower end of the post 3. As a result, there remains a slight gap between the two half-bases 2A, 2B. This is the reason why one of the half-bases is provided with a peripheral rim slightly projecting with respect to the junction plane and which constitutes a joint-cover making it possible to mask said space. The locking of the post 3, like that of the crossbar 7 or skirting 9 can be provided by means of screws passing through appropriate holes through one or other of the half-bases. These bores 2939463 -8- can be formed or roughed during the manufacture of the half-bases. They can be tapped. A second embodiment of the invention will now be described with reference to Figures 4 to 7, only in that it differs from the first embodiment. Figures 4 to 7 and 9 illustrate in particular a base 41, comprising two half-bases illustrated in detail in Figures 6 and 7. Figure 6 illustrates the left half-base 41A. Figure 7 illustrates the right half-base 41B. Figures 4, 5 and 9 illustrate three modes of implementation of the base 41.

As particularly shown in FIGS. 4 and 5, the base 41 is designed to be applied to an inner face of a parapet 42. Such an arrangement is particularly advantageous in that it makes it possible to install a guardrail , temporary or definitive, avoiding damage to a seal 43 already made on the slab 6.

As particularly illustrated in FIGS. 6 and 7, the base 41 comprises the same pole housing arrangements 18 as the base 2 of the first embodiment. Thus, a post 3 railing can, thanks to the same base 41, be placed substantially vertically, as shown in Figure 4, or tilted back, as shown in Figure 5.

As shown in FIG. 9, the base 41 can also be fastened to a surface on the outside of the parapet 42. In this particular embodiment, it is advantageous to envisage that the post housing is designed so that that the post may be inclined towards the plate, thus in the direction of the acroterium, instead of being inclined towards the rear, as illustrated in FIGS. 4 to 7. The base 41 is not intended to be placed on a horizontal plane, so that it does not include a sole. For the same reason, it does not include any provision for attaching a stabilizing spacer. A third embodiment of the invention will now be described with reference to Fig. 8 only in that it differs from the first or second embodiment. FIG. 8 illustrates a base 51 of monoblock type, ie unlike the bases previously described with reference to FIGS. 1 to 7 and 9, the base 51 is not made by the assembly of FIG. two half-bases. Thus, the post housing 18 is provided so that the post can be introduced therein without undue effort, preferably in an adjusted manner. The base 51 comprises a sole 11 and a plate 13. The plate 13 is raised from an anterior end of the sole 11, so that the plate and the sole together form a bracket. No housing is provided in the base for housing a stabilizer cross. Thus, the base 51 is essentially designed to be fixed by screwing, either on a slab or in applied. The body extends above the sole 11, so that a rear face of the body extends perpendicular to a rear end of the sole 11, and so that a space 53 is formed between the body 12 and the plate 13.

This space 53 is provided sufficiently deep longitudinally to accommodate two skirting boards and screw heads for the case where the base is fixed to apply. In the illustrated example, a boss 54 extends from the plate 13 in the space 53. This boss is intended to form a frontal support for the baseboards, so that the baseboards do not bear against the heads 20 screw. The bracket formed by the sole plate 11 and the plate 13 is provided sufficiently rigid so that the space 53 is open upwards, that is to say that the space 53 has a longitudinal section U. This This arrangement is particularly advantageous in that it facilitates the placement of skirting boards. The base 51 further comprises two bores 55, 56 coaxial about a longitudinal axis X51. A first piercing 55, of the two, extends between the housing 18 and the space 53. It is threaded and intended to receive a screw for blocking the baseboards in the space 53. The second piercing 56 extends between the housing 18 and a rear face of the body 12. It is smooth and intended for the passage of a wrench or a screwdriver for screwing the screw of 2939463 - 10 - blocking skirting. Such an arrangement makes it possible in particular to mask the locking screw, inside the body 12. The invention is not limited to the particular modes of manufacture described with reference to the figures.

In particular, arrangements for one embodiment may be combined with one another. Thus, a sleeper housing may be provided at the rear of a base incorporating the provisions of the second and third embodiments.

Also, an upper junction may be provided in a base incorporating the provisions of the third embodiment, or on the contrary, no upper junction be provided in a base incorporating the provisions of the first embodiment. In addition, the base according to the third embodiment may be provided in two half-bases, or those of the first two embodiments be provided in one piece.
